serialize() and unserialize()?
serialize() converts a PHP data structure (like an array or object) into a string that can be saved or transferred easily.
unserialize() takes that storable/transferrable string and converts it back into the original PHP data structure.
Commonly, you might store serialized data in a file or database, or send it across a network (although JSON is often used these days for broader compatibility).
